The answer is true, catalysts increase rates by lowering the activation energy of a reaction. Catalysts lower the reaction energy and so the reaction occurs faster. Enzymes perform the role of biological catalysts. Most metabolic pathways of the body are controlled by enzymes. Enzymes by classification are proteins. <span />
The lower the frequncy the longer the wavelength the longer the wavelength whoch would probably give you more energy.
if im incorrect im truly sorry
Answer: There are 
of 
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number 
of particles.
To calculate the moles, we use the equation:
Thus there are of
Ammonium Oxalate (NH4) 2c204 is the formula number and has a mass of 124.0959
Explanation:
3.Apply the ideal gas law: PV = nRT solving for n. Here you can use the pressure given in atm, but you must choose the 0.0821 atm L/mole K gas constant. Or you can change 4.5 atm to 3420 mm Hg and use the 62.4 mmHg L/mole K gas constant. You must change 500 ml to 0.5 L because both gas constants have units in L, and so the volume must be in liters so it can cancel out. And of course, you must change the temperature to Kelvin.
a. n = (4.5atm)(0.5L)
moliK)(298K) = 0.092 mole (0.0821 atmiL
b. 0.092mol 32g
⎛⎝⎜ ⎞⎠⎟ = 2.9 g
1mol
c. Remember that D = mass
vol so D = 2.9g
0.5L = 5.9 g/L
